Description

Technical Field

[0001] The present invention relates to the field of intelligent micro-break technology, and in particular to a method and system for identifying physical connection relationships of intelligent micro-breaks. Background Art

[0002] Smart micro-break technology integrates advanced technologies such as digitalization, the Internet of Things, and cloud computing to achieve real-time monitoring and precise control of circuit status. It can monitor key parameters such as voltage, current, and power of the circuit in real time. Once an abnormality is detected, it can cut off the power supply within milliseconds to effectively protect the safety of the line and equipment. Smart micro-breaks also have intelligent monitoring and early warning functions. Through built-in high-precision sensors and Internet of Things technology, circuit data can be analyzed in real time. Once an abnormality is detected, the early warning mechanism will be triggered immediately, and early warning information will be sent to the user through the built-in communication module. Smart micro-break switch products are widely used in user-side scenarios such as parks, communication rooms, street lights, etc., to support power safety, energy efficiency management, and intelligent operation and maintenance services in the substation area.

[0003] Traditional intelligent micro-breaks are usually a control panel with a switch to control the on and off of a transmission line. At the same time, the intelligent micro-break communicates with the gateway through the bus, and the gateway issues instructions for remote data collection or remote control. Therefore, the number of micro-break switches used for control is large and the cost is high. In order to present the micro-break connection relationship diagram of the entire campus building or computer room, in many cases, the connection relationship of the micro-break switches is identified by manual input or carrier characteristic current method.

[0004] Among them, the manual input method is time-consuming and laborious, and can only guarantee the accuracy of the connection relationship between switches in the initial state. With the increase or decrease of intelligent micro-breaks, the connection relationship between switches cannot be maintained. The problem of real-time changes in switch connection relationships can be solved by the carrier characteristic current method. However, due to interference and mutual influence between branches, the recognition accuracy is not high.

[0005] As for the connection relationship of intelligent switches, some people also obtain the connection relationship of switches by turning each switch on and off and then reading the status of other switches. Although this solution is simple, the number of operations is n*(n-1)…*1=n! As the number of switches increases, the complexity increases geometrically, and it is not applicable when the number of switches is large. Summary of the invention

[0006] The present invention provides an intelligent micro-break physical connection relationship identification method and system, which are used to solve the defects of low efficiency and low precision in the prior art of micro-break switch connection relationship identification, thereby improving the recognition efficiency of micro-break switch connection relationships and improving the connection relationship identification accuracy.

[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0047] The following will describe Figure 1 an intelligent micro - breaker physical connection relationship identification method of the present invention, including:

[0048] Step 101, selecting a single switch from switches mounted under the current smart micro-breaker in the smart micro-breaker to be identified, and sending a characteristic current to the selected switch in the current smart micro-breaker through a sending component in the current smart micro-breaker;

[0049] Step 102, obtaining recognition results of the characteristic current by switches of other intelligent micro-breaks among the intelligent micro-breaks to be identified except the current intelligent micro-breaks;

[0050] Step 103, determining the connection relationship between the switches in the to-be-identified intelligent micro-breaks according to the identification result of the characteristic current of the selected switch in the to-be-identified intelligent micro-breaks;

[0051] Step 104: When the connection relationship between the switches of the to-be-identified intelligent micro-breaks does not meet a preset condition, the connection relationship is corrected.

[0052] The smart micro-break network mainly includes two main devices, the multi-service gateway and the smart micro-break. The two main devices are connected to the multi-service gateway and the last-level smart micro-break respectively. The multi-service gateway runs the topology identification APP to realize the control and calculation logic functions. As an execution unit, the smart micro-break receives commands from the multi-service gateway, starts the characteristic current identification function, and generates characteristic small current as needed. Each smart micro-break is mounted with one or more switches. Multiple switches under the same smart micro-break are connected in parallel.

[0053] like Figure 2 As shown, four composite switch-type intelligent micro-breaks form a topology through upper and lower interconnection, where micro-break 1 (including switch 1 and switch 2) is the first level, micro-break 2 (including switch 3, switch 4, switch 5 and switch 6) and micro-break 3 (including switch 7 and switch 8) are the second level, and micro-break 3 (including switch 9 and switch 10) is the third level.

[0054] The multi-service gateway sends a topology identification command to all the intelligent micro-breaks to be identified {K1, K2, K3…} to start topology identification. The multi-service gateway selects a switch for each intelligent micro-break to be identified and controls the sending component in each intelligent micro-break to be identified to send the characteristic current serially. After sending the characteristic current to the previous intelligent micro-break to be identified and completing the identification, the characteristic current is sent to the next intelligent micro-break to be identified. The multi-service gateway also records the time point when the characteristic current is sent by name. This time point is used for subsequent topology result comparison and analysis.

[0055] For example, select switch S1 for miniature circuit breaker K1, send a command to switch S1, and name switch S1 to send characteristic current. After a period of time, such as 30 seconds, poll miniature circuit breaker K2, select switch S4, and name switch S4 to send characteristic current. The duration of sending the characteristic current can be about 9.6 s. It can be delayed for 30 s to wait for the completion of the identification of the characteristic current and query the identification result. Poll the next intelligent miniature circuit breaker to be identified under any name until all the intelligent miniature circuit breakers K1 to Kn to be identified are identified.

[0056] For the switches of other intelligent miniature circuit breakers except the current intelligent miniature circuit breakers among the intelligent miniature circuit breakers to be identified, identify the characteristic current to obtain the identification result. Analyze the identification results returned by the multi-service grid miniature circuit breakers to obtain the connection relationship between the switches of the miniature circuit breakers. If the first-round identification result is correct, end the topology identification process and output the topology identification result.

[0057] When the connection relationship between the switches of the intelligent miniature circuit breakers to be identified does not meet the preset conditions, it indicates that there is signal interference. Determine the existence of doubtful switches, send characteristic current to the doubtful switches to re-identify the connection relationship, or determine the accurate connection relationship by the switch-off method.

[0058] In this embodiment, by first using the characteristic small current method to quickly identify a relatively accurate connection relationship diagram of intelligent miniature circuit breakers, and then using the switch characteristics of intelligent miniature circuit breakers to determine the accurate connection relationship for the doubtful connection relationships, and for the composite switch type intelligent miniature circuit breakers, only select a single switch from each miniature circuit breaker to identify the characteristic current, thereby improving the identification efficiency and accuracy of the connection relationship of intelligent miniature circuit breakers.

[0059] Based on the above embodiment, in this embodiment, determining the connection relationship between the switches of the intelligent miniature circuit breakers to be identified according to the identification result of the characteristic current of the selected switch in the intelligent miniature circuit breakers to be identified includes:

[0060] According to the identification result of the characteristic current by the switches of the other intelligent miniature circuit breakers, determine that there is a connection relationship between the switches of the other intelligent miniature circuit breakers and the selected switch in the current switch;

[0061] Determine the number of switches having a connection relationship with the selected switch when sending characteristic current to the selected switches in each intelligent miniature circuit breaker to be identified;

[0062] According to the number of switches having an identified connection relationship corresponding to the selected switches in each intelligent miniature circuit breaker to be identified, determine the levels of the intelligent miniature circuit breakers to be identified. The lower the number of switches having an identified connection relationship, the higher the level;

[0063] Use the switches in the upper level of each intelligent miniature circuit breaker to be identified that have an associated relationship with the selected switches of each intelligent miniature circuit breaker to be identified as the parent switches of the switches in each intelligent miniature circuit breaker to be identified.

[0064] Under normal circumstances, when a characteristic current is sent to the selection switch of the current intelligent miniature circuit breaker, the characteristic current is transmitted upward. Only the intelligent miniature circuit breakers in the upward direction of the current intelligent miniature circuit breaker switch can recognize the characteristic current, while the intelligent miniature circuit breakers in the downward direction cannot recognize the characteristic current, thereby determining the switches having a connection relationship with the selection switch.

[0065] For example, Figure 2 when the switch 7 in the intelligent miniature circuit breaker 3 sends a characteristic current, the recognition module in the switch 1 of the intelligent miniature circuit breaker 1 can recognize the characteristic current, while the switches in the intelligent miniature circuit breakers 2 and 4 cannot recognize the characteristic current. Therefore, it is determined that there is a connection relationship between switch 1 and switch 7.

[0066] After sending a characteristic current to the selection switches in all the intelligent miniature circuit breakers to be recognized for recognition, when determining the characteristic current sent to the selection switches in each intelligent miniature circuit breaker to be recognized, the number of switches having a connection relationship with the selection switch is obtained, thereby determining the switch hierarchy and the connection relationship between switches.

[0067] For example, when a characteristic current is sent to switch 1 selected in the intelligent miniature circuit breaker 1, no switch can recognize the characteristic current, and the number of switches having a connection relationship with switch 1 is 0. When a characteristic current is sent to switch 4 selected in the intelligent miniature circuit breaker 2, the switch 1 in the intelligent miniature circuit breaker 1 can recognize the characteristic current, and the number of switches having a connection relationship with switch 4 is 1. When a characteristic current is sent to switch 7 selected in the intelligent miniature circuit breaker 3, the switch 2 in the intelligent miniature circuit breaker 1 can recognize the characteristic current, and the number of switches having a connection relationship with switch 7 is 1. When a characteristic current is sent to switch 9 selected in the intelligent miniature circuit breaker 4, the switch 7 in the intelligent miniature circuit breaker 3 and the switch 2 in the intelligent miniature circuit breaker 1 can recognize the characteristic current, and the number of switches having a connection relationship with switch 9 is 2.

[0068] Taking the intelligent miniature circuit breaker 1 to which switch 1 with the number of switches being 0 belongs as the first level, taking the intelligent miniature circuit breaker 2 to which switch 4 with the number of switches being 1 belongs and the intelligent miniature circuit breaker 3 to which switch 7 belongs as the second level, and taking the intelligent miniature circuit breaker 4 to which switch 9 with the number of switches being 2 belongs as the third level. Since switch 4 has a connection relationship with switch 1 in the first level, switch 1 is the parent switch of the switch under the intelligent miniature circuit breaker 2. Since switch 7 has a connection relationship with switch 2, switch 2 is the parent switch of the switch under the intelligent miniature circuit breaker 3. Since switch 9 has a connection relationship with switch 7 in the second level, switch 7 is the parent switch of the switch under the intelligent miniature circuit breaker 4.

[0069] Based on the above embodiments, in this embodiment, the recognition result includes signal strength and background noise. Determining that the switch of the other intelligent miniature circuit breaker has a connection relationship with the selection switch in the current switch according to the recognition result of the switch of the other intelligent miniature circuit breaker on the characteristic current includes:

[0070] When the signal intensity of the characteristic current identified by the switch of the other intelligent miniature circuit breaker is greater than the first preset threshold and the background noise is less than the second preset threshold, it is determined that there is a connection relationship between the switch of the other intelligent miniature circuit breaker and the selector switch in the current switch.

[0071] In each topology recognition result, in addition to the signal intensity and background noise, it also includes the moment when the characteristic current is sent and the switch address where the characteristic current is detected, which is used to judge which switch of the miniature circuit breaker detects the characteristic current sent by the switch and is used to draw the final connection relationship diagram of the miniature circuit breaker.

[0072] On the basis of the above embodiments, in this embodiment, the preset condition is that the number of parent switches of each switch in the intelligent miniature circuit breaker to be recognized is less than 2. When the connection relationship between the switches of the intelligent miniature circuit breakers to be recognized does not meet the preset condition, the connection relationship is corrected, including:

[0073] If there is a first switch with multiple parent switches in the connection relationship, then according to the on-off state of the doubtful switch when the on-off states of the parent switches of the first switch are off, it is determined whether each parent switch is the final parent switch of the doubtful switch.

[0074] For the miniature circuit breaker with composite switches, since there are multiple switches in each miniature circuit breaker, if topology relationship recognition is performed on each switch, it will inevitably increase the entire connection relationship recognition cycle, bringing great inconvenience to operation and maintenance. Assuming the number of switches is n1, it is expected to take about 30 seconds for each switch to send a characteristic current plus recognize the characteristic current, and the entire recognition process takes about n1 * 30 seconds.

[0075] In this embodiment, in the first round, the connection relationship is initially confirmed through the characteristic current, which takes about 30 * n2 seconds, where n2 is the number of intelligent miniature circuit breakers, and the accuracy is more than 90%. The remaining switches with failed recognition usually have two or more parent switches recognized for that switch, resulting in a doubtful connection relationship.

[0076] At this time, the connection relationship of the doubtful switch is confirmed by separately performing an off operation on the parent switches of the doubtful switch. This operation takes an average time of where m is the number of intelligent miniature circuit breakers to which the remaining 10% of the doubtful switches belong, and p i is the number of parent switches of the doubtful switch in the i-th intelligent miniature circuit breaker.

[0077] For example, analyze the connection relationship output by the characteristic current method, and identify the doubtful switch and its list of parent switches {(S1: S1u1, S1u2), (S2: S2u1, S2u2)…(Sm: Smu1, Smu2)}.

[0078] For the suspect switch S1, disconnect its parent switch S1u1, and detect the on / off state of the suspect switch. If it is found that the state of switch S1 is also off, then confirm that S1u1 is the parent switch of S1; otherwise, continue to disconnect S1u2, and so on, until the connection relationship is confirmed. The actual test shows that after this operation, the recognition accuracy of the connection relationship of the miniature circuit breakers reaches more than 99%.

[0079] In this embodiment, through the method combining the characteristic small current method and the switch on / off detection, the automatic recognition of the connection relationship between the intelligent miniature circuit breakers in the park building or computer room is quickly realized, which not only greatly reduces the time for recognizing the connection relationship, but also greatly improves the recognition accuracy of the connection relationship. According to the connection relationship of the intelligent miniature circuit breakers (switches), it provides strong support for subsequent accurate fault location, solving the overload of electrical facilities, and solving the three-phase imbalance service, and further realizes the ultimate goals such as the electrical safety and energy saving and efficiency improvement in places such as residential buildings and office buildings, which helps to realize the remote operation and maintenance of smart parks or intelligent computer rooms.

[0080] On the basis of the above embodiment, the preset condition in this embodiment is that each switch in the to-be-recognized intelligent miniature circuit breaker has a connected switch. When the connection relationship between the switches in the to-be-recognized intelligent miniature circuit breakers does not meet the preset condition, the connection relationship is corrected, including:

[0081] If there is a second switch in the connection relationship that has no connection relationship with any switch, then select a single switch from the to-be-recognized intelligent miniature circuit breaker to which the second switch belongs to send a characteristic current again, obtain the recognition result of the characteristic current of the re-selected switch, and determine the switch that has a connection relationship with the second switch according to the recognition result of the characteristic current of the re-selected switch.

[0082] If it is found in the first round that the connection relationships of some switches are not recognized, it means that there is signal interference. Then, start the second round of recognition process for the unrecognized switches and repeat the relationship recognition steps. If there are still some switch connection relationships that are not recognized, then perform the third round of recognition until the preset execution times are reached.

[0083] On the basis of the above embodiment, in this embodiment, obtaining the recognition results of the switches of other intelligent miniature circuit breakers except the current intelligent miniature circuit breakers in the to-be-recognized intelligent miniature circuit breakers includes:

[0084] Obtain the signals modulated by the characteristic current of the switches of other intelligent miniature circuit breakers except the current intelligent miniature circuit breakers in the to-be-recognized intelligent miniature circuit breakers, and obtain the recognition results from the modulated signals.

[0085] The presence or absence of the characteristic current can be achieved through OOK modulation to represent "1" and "0" of the digital signal. The modulation carrier frequency f1 is the switching frequency for transmitting the characteristic signal. After modulation, the original information becomes the signal:

[0086]

[0087] Among them, A represents the amplitude of the characteristic current, and DUTY represents the duty cycle of the characteristic signal. The modulation carrier frequency is f1, and the duration of each bit is the set bit width time. If the bit is 1, it is modulated with the frequency f1 within the duration of this bit; if the bit is 0, no modulation is performed.

[0088] The modulation carrier frequency can default to f1 = 833.3 Hz, and the duration of each bit can be 0.6 s. The peak value of the characteristic current sent by the sending component should not be greater than 0.60 A, and the effective value of the characteristic current when the characteristic code bit is 1 should not be less than 0.21 A.

[0089] Based on the above embodiments, in this embodiment, before selecting a single switch from the switches mounted under the current intelligent miniature circuit breaker in the intelligent miniature circuit breaker to be recognized, it further includes:

[0090] Search through the carrier modules built in each intelligent miniature circuit breaker to be recognized to obtain the switches mounted under each intelligent miniature circuit breaker to be recognized and the addresses of these switches;

[0091] Register each intelligent miniature circuit breaker to be recognized according to the addresses of the switches under each intelligent miniature circuit breaker to be recognized;

[0092] Establish a correspondence table between the intelligent miniature circuit breaker to be recognized and the switches according to the MAC address of the carrier module and the addresses of the registered switches;

[0093] Query the relationship correspondence table to obtain the switches mounted under the current intelligent miniature circuit breaker.

[0094] There is a built-in carrier module in the intelligent miniature circuit breaker to be recognized. After the intelligent miniature circuit breaker to be recognized is started, the carrier module automatically searches for the table, detects all the switches hung under this circuit breaker, and caches the switch addresses for registration.

[0095] The intelligent miniature circuit breaker to be recognized registers the switches with the intelligent gateway through the MINI carrier module, and registers all the switch addresses found under this circuit breaker to the multi-service gateway.

[0096] If the registration is successful, according to the MAC of the carrier module registered as an agent and the registered switch addresses, an automatic correspondence table between the circuit breaker and the switches is established, such as {(K1:S1,S2);(K2:S3,S4,S5,S6);(K3:S7,S8);…}.

[0097] The multi-service gateway sends topology recognition commands to all miniature circuit breakers {K1, K2, K3...} to start topology recognition. The multi-service gateway queries the correspondence table of miniature circuit breakers and switches, and names and sends characteristic currents. No matter how many switches a miniature circuit breaker has, it only needs to be named once.

[0098] The working flow chart of automatic physical topology recognition of intelligent miniature circuit breakers is as Figure 3 shown. The multi-service gateway runs the topology recognition APP to implement control and calculation logic functions, including: registration of intelligent miniature circuit breakers (switches); precise time calibration to ensure that the time of all miniature circuit breakers in the area is the same, maximizing the accuracy of characteristic current recognition; starting characteristic current recognition; naming intelligent miniature circuit breakers to send characteristic currents; on-off operations of doubtful switches; analysis and calculation of recognition results.

[0099] Each intelligent miniature circuit breaker to be recognized is built with a MINI carrier module, a characteristic current sending component, and a recognition module. First, a relatively accurate connection diagram of intelligent miniature circuit breakers is quickly recognized through the characteristic small current method, and then, using the characteristics of intelligent miniature circuit breaker switches, the doubtful connection relationships are determined by turning off the switches, thus achieving good results in improving recognition efficiency and accuracy.

[0100] Based on the above embodiments, in this embodiment, before sending the characteristic current from the sending component in the current intelligent miniature circuit breaker to the selected switch in the current intelligent miniature circuit breaker, it further includes:

[0101] Calibrating the intelligent miniature circuit breaker to be recognized so that the clocks of the intelligent miniature circuit breakers to be recognized are consistent.

[0102] Next, the intelligent miniature circuit breaker physical connection relationship recognition system provided by the present invention is described. The intelligent miniature circuit breaker physical connection relationship recognition system described below can be correspondingly referred to the intelligent miniature circuit breaker physical connection relationship recognition method described above.

[0103] As Figure 4 shown, the system includes a sending module 401, an acquisition module 402, a determination module 403, and a calibration module 404, where:

[0104] The sending module 401 is used to select a single switch from the switches mounted under the current intelligent miniature circuit breaker among the intelligent miniature circuit breakers to be recognized, and send a characteristic current from the sending component in the current intelligent miniature circuit breaker to the selected switch in the current intelligent miniature circuit breaker;

[0105] The acquisition module 402 is used to acquire the recognition results of the switches of other intelligent miniature circuit breakers except the current intelligent miniature circuit breakers among the intelligent miniature circuit breakers to be recognized for the characteristic current;

[0106] The determination module 403 is configured to determine the connection relationship between the switches of the to-be-identified intelligent miniature circuit breakers according to the recognition result of the characteristic current of the selection switch in the to-be-identified intelligent miniature circuit breakers;

[0107] The correction module 404 is configured to correct the connection relationship when the connection relationship between the switches of the to-be-identified intelligent miniature circuit breakers does not meet the preset conditions.

[0108] In this embodiment, a relatively accurate connection relationship diagram of intelligent miniature circuit breakers is quickly recognized by using the characteristic small current method first, and then the accurate connection relationship of the doubtful connection relationships is determined by using the switch characteristics of the intelligent miniature circuit breakers.
